I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Try to use them!  

First, you can look them up on php.net, and you should always do that any time you are not 100% dead-certain (1) what inputs are required, (2) how they work, (3) what outputs and return values are expected.  Always read the online man pages and pay attention to the user-contributed notes that are some of the best parts of php.net.  Here are the links you want to study:
